Digital Refractometer Saber LED with Three Scales, Waterproof (Brix, Sugar, Specific Gravity)

Saber LED Refractometer with three scales, waterproof (includes case and charging cable)

Getting quick, accurate, and reliable readings throughout the malt beer brewing process is crucial for achieving the best possible efficiency. A refractometer helps you achieve this and can significantly speed up your brewing day. Now in a waterproof design that's rechargeable!

This high-quality refractometer is extremely accurate and easy to use and calibrate. Calibration is done simply using a few drops of distilled water and a flathead screwdriver. This model also includes automatic temperature compensation (ATC).

Package includes:
- Carrying case
- Red magnetic charging cable
- USB charging cable (AU plug not included)

Calibration steps:
1. Add 10 drops of clean filtered water (preferably deionized water) to the refractometer's sample prism
2. Either in direct sunlight or using LED illumination, observe the blue-shaded area. Does it show 1.000? If it's higher or lower, use a flathead screwdriver to adjust the bottom of the Saber refractometer until it reads 1.000.

• Around 1000-1010: low sugar content, fermentation is complete or nearly complete
• 1040-1060: normal Original Gravity for beer
• 1070-1090: higher alcohol content beers
• 1080-1130: very sugar-rich liquids, such as some mead mixtures or concentrated wine musts

Refractometer operating principle: The device measures the refractive index of liquid, which changes with the concentration of sugar or other dissolved substances. This allows brewers to monitor sugar content throughout the brewing process, providing accurate readings without interrupting the brewing process.
